The direct answer

Audit Google Ads in this order: confirm the business goal, validate conversions, reconcile lead or order quality, review search intent, inspect landing pages, and assess budget constraints. Rank findings by evidence and business impact. Fix an unreliable measurement signal before you use it to justify more spend.

1. Define the business outcome and comparison period

Ask what a valuable conversion means for this business. A form fill, a qualified lead, a booked appointment, and a paying customer describe different outcomes. Ecommerce teams also need a consistent treatment of discounts, returns, tax, and repeat customers.

Use a period that includes the normal conversion delay and enough completed outcomes to support a decision. Compare like-for-like weekdays, markets, and offers. Mark promotions, tracking changes, stock shortages, and budget shifts. A weak recent week can reflect incomplete conversions rather than worse demand.

  • Write down the primary business goal and the agreed definition of success.
  • Confirm the account, currency, time zone, markets, and review dates.
  • Collect change history, conversion definitions, and the relevant sales or order records.
  • Record missing inputs before you calculate opportunity or savings.

2. Check what the account counts as success

Inspect each conversion action, its source, value, counting setting, and role in campaign goals. Check for duplicate events, test submissions, page views counted as leads, and outdated goals. A real form submission is still not proof of a qualified sales opportunity.

Google distinguishes primary and secondary conversion actions. Primary actions can feed bidding when their goal applies. Secondary actions generally support observation, but custom goals can change that behavior. Inspect the campaign's actual goal setup, not just the account-level label.

  • Trace one completed customer journey from the website to the recorded conversion.
  • Compare Google Ads outcomes with the business's lead or order records using the same definitions.
  • Check conversion delay before judging recent performance.
  • Do not assume every reporting mismatch means tracking is broken. Dates, attribution, and scope can differ.

3. Separate cheap conversions from useful outcomes

For lead generation, compare qualification and closed sales by campaign or intent group where attribution is available. Record invalid contacts, wrong service areas, duplicates, and unsuitable requests separately. This gives the team a reason for poor quality that it can act on.

For ecommerce, compare the revenue reported in the account with net sales and contribution after variable costs. Check whether a high reported return depends on repeat buyers or a low-margin product mix. Use the same revenue basis for your target and reported ROAS.

ROAS risesNet revenue, variable costs, returns, and customer mixWhether the additional sales create contribution

4. Read the searches and the destination together

Group visible search terms by the buyer's purpose: the brand, a specific service, a comparison, a problem, or an unsuitable request. Read the matching ad and landing page together. A relevant query can still reach a page that answers a different question.

The search terms report omits some queries under Google's privacy rules. Keep the unreported share visible. You cannot describe the visible rows as a complete view of every search or assign the hidden queries a guessed intent.

  • Flag clearly irrelevant terms for review and check exclusions for accidental loss of relevant demand.
  • Review location and network settings against the business's real service area and sales model.
  • Inspect the exact destination on mobile, including form fields, errors, and the next step.
  • Separate an irrelevant query from a useful query with weak page fit. The fixes differ.

5. Rank decisions before changing spend

A budget limit describes a delivery constraint. It does not prove that more spend will meet the business's margin or lead-quality target. Review outcome quality, the return on recent additional spend, and delivery capacity before scaling.

Use a simple decision order. First repair evidence that could mislead the team. Then address confirmed waste or a broken journey. Next test promising opportunities with a clear comparison. Hold work that needs missing data. Assign one owner and a review date to each item.

6. Close the audit with a plan the team can use

For every recommendation, include the source, review period, confidence, affected campaign or page, expected mechanism, owner, and next check. State what remains unmeasured. A finding with incomplete customer outcomes needs a validation step before a savings claim.

Keep the original baseline and record the actual launch date. Reassess after the relevant conversion delay. If several changes launch together, the team may see an overall change without knowing which action caused it. Keep tests narrow when attribution matters.

Common questions

What should a Google Ads audit include?

Include the business goal, conversion setup, customer outcome quality, search intent, landing-page fit, campaign settings, and budget constraints. Finish with ranked actions, source evidence, owners, and a way to measure each change.

Should you pause every keyword with no conversions?

No. First check spend, relevance, conversion delay, reporting completeness, and the business's buying cycle. An irrelevant term and a relevant term with too little mature data need different decisions.

How often should you audit Google Ads?

Review measurement after site or goal changes. Run a broader audit before major budget changes, agency handoffs, or a new planning cycle. Set the review rhythm around conversion delay and the pace of account change.
